UNrrED STATES ROBERT HENKEL, OF PROVIDENCE, RHODE ISLAND.

PAN SCRAPING AND CLEANING MACHINE,

SPECIFICATION forming part f Letters Patent NO. 672,554, dated April 23, 1901.

Application iiled December 28, 1900. Serial No. 41,368. .No modem To all whom t may concern:

Beit known that I, ROBERT HENKEL, a citizen of the United States of America, and a i resident of the city and county of Providence,

p head or spider having a series of pivotallymounted self-ad j listing blades attached thereto adapted to conform within fixed limits to the beveled sides and bottom of the interior surface of the pan, whereby upon pressing the pan against the outer or peripheral edge of the revolving blades the latter operate to quickly scrape offand remove any particles of cake, bread, grease, dac., adhering thereto from the previous baking, all as will be more fully hereinafter set forth and claimed.

In bakeries, hotels, and other establishments where comparatively large quantities of cakes-as, for example, cup-cakes, cupcustards, (lneare produced daily it is well known that in order to render the inner surface of the pans or tins perfectly smooth and clean after the cooked contents have been removed therefrom considerable time and labor must be consumed, and even then the result is more or less unsatisfactory. By means of my improved pan-cleaning machine the attendant is enabled to scrape and clean the pans in a much more expeditions and satisfactory.

manner and at a considerably-lessened cost.

In the accompanying sheet of` drawings, Figure l is a side elevation., in partial section, of a pan-cleaning machine embodying my improvement. Fig. 2 is a side view of the head or spider detached from the machine, and Fig. 3 is a plan view of it.

A, again referring to the drawings, designates my improved pan scraping and cleaning machine as a whole.` The standard or frame a thereof has a base portion a', adapted to be secured to a table, sink, or other suitable support. The upper portion of the frame is drilled to receive and form a step and bearing for the vertical spindle b. Rotary movement may be imparted to the spindle by means of the large bevel driving gear-wheel c, mounted ona stud a3, secured to and exg tending from the side of the standard a, and the intermeshing pinion-gear c', fixed to the said spindle. The driving-gear may be rotated by means of a handle h, or it may be driven by power transmitted through a travcling belt passing around the score-pulley 19, fixed to the gear. In the latter case it is obvious that the handle should be first removed. The spindle extends upwardly beyond the pinion c', so as to freely receive and drive the head or spider d, the lower end `of the latter being slotted to receive the fixed pin or key b2 of the spindle, as clearly shown. As drawn the head member is provided with a series of four longitudinallyextending win gs d', arranged at substantially right angles with its axis. At or near the center of each wing is located a swinging pivotally-mounted blade or scraper c, made-of suitable material,as sheet-steel. These blades extend above the top end of the head d and also inwardly toward the center. The outer or peripheral edge mot' the blade is inclined, so as to conform to the flaring sides of the pan or tin. In the drawings I have represented the device as more especially adapted to clean cup-cake pans-that is, pans having considerable depth, but being comparatively small in diameter. It will be seen that the inner edges of the blades are beveled in opposite directions from the pivot point or screw s, as indicated at e and e2, the arrangement being such that the blades automatically adapt themselves, within certain limits, to pans having flaring sides varying in degree; or, in other words, when the upper beveled edge portions c bear against the adjacent vertical surfaces b3 or hub of the spider the machine is then adapted to pans whose sides have the greatest inclination, and conversely when the lower beveled portions e2 bear against said vertical surfaces b3 the machine is adapted to pans having sides much less angular. (See dotted-line position in Fig. 2.) Thus it will be seen that to a certain extent the machine is self-adjusting with respect t0 the diameter of the pans and also to their flaring sides.

The manner of operating my machine for IOO ' from the latter to the table or base.

scraping and cleaning cake-pans may be described as follows: The attendant places the pan f inverted over the top of the revolving head portion, at the same time yieldingly pressing it against the outer edges of the blades. These in turn act quickly to remove any burned or foreign matter from the sides and bottom of the pan, thereby rendering the latter clean and bright. The matter removed from the pan falls onto the guard g below and This guard, it may be observed, further serves to prevent the scrapings from dropping into .the gearing. The head d may be fitted or provided with several series of blades varying in size and shape, the substitution of one set of blad es for another being readily effected when desired by simply removing the pivotscrews s and mounting thereon the substitute blades, followed by resecuring the screws to 2o the head..

I claim as my invention and desire to secure by UnitedStates Letters Patent- The pan-cleaning machine herein before described,thesameconsistingofaframeorstandz5 ard, a pair of bevel-gears, c, c', spindles as, b, on which said gears are respectively mounted, and a head or spider, removably secured to the spindle b, having a series of suitably-shaped seraperblades e pivoted thereto, substantially as hereinbefore described and shown and for the purpose set forth.

Signed by me, at Providence, Rhode Island, this 27th day of December, A. D. 1900.

ROBERT HENKEL.
